When your furnace is operating properly, it should provide warmth without creating too much noise. While it’s expected to catch your furnace making noise as it turns on, other noises are indicating your furnace should get immediate professional assistance.
Here are some of the most frequent furnace noises and what they might be indicating. If your furnace is making a strange noise, our friendly heating pros are here to help with the best furnace repair in Swanton, Ohio.
1. Furnace Makes a Banging Sound
You may have a serious issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be a few problems. These range from gas building up in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system becomes dirty as time passes, so that’s why it’s important to book annual furnace maintenance with Northwest Services. One of the jobs our professionals do during this service is clean your furnace’s burners. When this piece gets grubby, you may hear your furnace making a loud rumbling noise when ignition takes longer than normal. The subsequent gas buildup might break your furnace’s heat exchanger, where natural gas changes into heat. Any cracks in it can leak carbon monoxide, which is ordinarily released away from your home. This toxic gas can be lethal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Northwest Services recommends turning it off and calling us at 419-548-5017. Excessive natural gas in your furnace or a broken heat exchanger are serious problems that necessitate immediate attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver heated air throughout your house. If the ductwork wasn’t installed correctly or is aging, it can be loud when your furnace runs. This can be the issue if your furnace makes a banging noise when it shuts off. Call Northwest Services at 419-548-5017 and we’ll figure out the problem.
2. Furnace Makes a Buzzing Sound
If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound often indicates an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to operate on the proper voltage. If wires or the box is loose, you could hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves warm or cooled air throughout your space, and a capacitor, which triggers the motor. If either of these pieces are fading, they will buzz when the furnace switches on.
3. Furnace Rattles
If your furnace is making a rattling noise, it can be due to something small, like a loose screw, or something critical, like a broken component. In either case, we advise shutting your furnace off and getting in touch with our heating professionals at 419-548-5017 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to alert you it requires some TLC. If you’ve skipped furnace maintenance recently, belts could be worn out or a bearing may need to be lubed. We know that maintenance often slips your mind, but our pros can get your furnace operating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You may also be aware of whistling while the furnace is working if a floor vent is loose. If you’ve examined your vents but are still noticing whistling, Northwest Services can assist you. It’s critical to get loose ductwork taken care of quickly, since it can result in comfort problems in your home and inflate your heating expenses.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal racket often means there’s a problem with your furnace’s blower. Turn off your furnace off instantly and reach us at 419-548-5017 for help.
